- CA 11:34 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: MityDSP boot problem
- Hi Greg,
Actually this was the page I referenced while I was working on u-boot. In the page, two solutions are suggested. The first one is the _bootdsp_ command which only works for _COFF_ binaries. Being Achilles' heel of the solution,... - GG 10:15 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: MityDSP boot problem
- Hi Caner,
Have you looked at our wiki page ([[DSP_Quick_Start|DSP Programming Quick Start]]) for launching the DSP without utilizing the ARM? If I am understanding your end goal this may be helpful to you.
Thanks,

- Hi,
I followed the instructions in https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Das_U-Boot_Port:
I fetched files from the git repo

- It was my understanding that he was trying to build the UBL. In which case the source code is located at MDK_2014-01-13/sw/3rdparty/OMAP-L138_FlashAndBootUtils_2_27

- Hi Caner,
Regarding U-Boot, the source code for the MityDSP-L138 U-Boot we use can be found on our support site in this git repository: http://support.criticallink.com/gitweb/?p=u-boot-mitydspl138.git;a=summary
Our wiki also has in...

- Hi,
We're working on a DSP software on MityDSP_OMAP-L138 board without BIOS and we do not intend to use ARM side in near future. We use COFF libraries whose ELF versions do not exist, thus we are unable to flash the DSP directly appylin... - MK 03:25 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: Accessing git repositories when behind firewall
I found a good solution which might be worthwhile sharing :)

- DV 02:19 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: 8TB USB Mass Storage device being unreadable
- Hi Dominik,
Glad you found the solution! I know I've spent many hours working on kernel issues to have them solved with one line changes.
Thank you for the update!

- Hey Dan!
I found the culprit! :)
As it often happens in linux kernel, the solution turns out to be very trivial.
It requires enabling CONFIG_LBDAF, which extends kernel partition device sector count width from 32 to 64 bits.

- Hi Dominik,
The only thing I could really think of was try the very verbose USB output like you initially suggested or add printk's to the USB driver. Try it with a flash drive and then the 8TB devices and compare the outputs.
I'm ... - DM 09:20 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: 8TB USB Mass Storage device being unreadable
- Hey Dan,
Thanks for your reply.
Building CHR_DEV_SG into mitysom kernel doesn't seem to fix anything. The SG initialization message appears now though. I've also tried to use /dev/sg0 device as the dd input with and without DEV_SD dr... - DV 11:51 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: GPIO pins high during Pre-loader/Uboot 5CSE-H4-3YA
- Hi Brian,
Unluckily the initial values of the GPIOs aren't configurable from what I've seen. You could edit board/cl/mitysom-5csx/mitysom-5csx.c and in the board_init function set the GPIOs values but I'm not sure how long it takes to...

- Hello,
I have a project where I hooked up leds to several gpio lines. The gpio lines go high for about 5 seconds (which is not acceptable for this application) during what seems to be the preloader/uboot stage and then go low once the...
